Details

The G7 nations have agreed on a common terminology system that distinguishes Open-source AI from Open-weights AI for the purpose of AI regulation and policy-making.

This measure is intended to prevent misuse of the term 'open source' based on technical characteristics, and to clearly define the level of openness of a model.

This agreement is expected to serve as an important standard in each government's future AI regulatory frameworks and policy-making processes.
